METHOD FOR THE CHEMICAL DECONTAMINATION OF METALLIC PARTS OF REACTOR INSTALLATIONS

摘要

Chemical decontamination of metallic parts of nuclear reactor installation in which an oxidative treatment with a permanganic acid solution is applied before dicarbonic acids are used for further treatment. Rinsing operations are eliminated and smaller amounts of dicarbonic acids needed. Also the primary system of the nuclear reactor no longer requires emptying before effecting decontamination treatment. 14
